This invention relates to a medical injecting apparatus and moreparticularly to a medical device for simultaneously injecting into andextracting fluids from the body.

In the medical art, various types of syringes and medical apparatus areused for extracting iluids from and injecting others into the body.These types of apparatus usually contain a syringe with a multiple-wayvalve and a syringe needle so that by operating the valve, once theneedle has been inserted into any desired part of the body, the fluid iswithdrawn by means of one of the syringes from the body, and after thisoperation has been completed, one of the other syringes containingfluids of any suitable kind, depending upon the kind of operation beingperformed by the physician, is forced into the body through said syringeneedle. It is apparent that this process is tedious with this type ofapparatus since there is no provision in such type of apparatus for asimultaneous extraction of fluid from the body and injection ofnecessary fluid into the body.

With the above disadvantages in view, it is a primary object of myinvention to provide an.

easily operable medical device which permits simultaneous extraction ofiluid of one kind from the body and simultaneously injecting a fluid ofanother kind into the body.

Another object of the present invention is to provide an easilyassembled, simply and economically made medical device having a dualchannel adapted for injecting gaseous or liquid fluids through onechannel into the body while simultaneously withdrawing through the otherchan' nel fluid of another type from the body.

A specic object of the present invention is to provide a medical devicecomprising a body member with a multiple-way valve and multiplechanneled needle and an operable fluid regulator in connection with saidvalve.

A more specific object of my invention is to provide a medical devicecontaining a body member to which may be attached a plurality ofsyringes, and a fluid regulator, and a needle integral with the bodymember having a pair of independent channels one of which is in directcommunication with the fluid regulator and the other in selectivecommunication with the syringes.

Other objects, advantages and features will become apparent from thehereinafter described invention taken in connection with theaccompanying drawings in which;

Fig. 1 is a sectional view of a preferred embodiment of my invention;

Fig. 2 is a sectional view of my invention containing intake iiuidregulating means for controlling the amount of iluid intake into thebody;

Fig. .3 is an enlarged detail sectional view of a portion of theembodiment, shown in Figs. 1 and 2; and f Fig. 4 is a sectional viewtaken on line 4-4 of Fig. 3.

Referring now to the drawings in which like reference numerals refer tolike parts throughout, it will be noted that I provide a medical deviceI0 containing a body member I I, provided with a plurality of inlets I2,I3 and I4, respectively, and passages I 5, I 6, and I1, respectively,for said inlets I2, I3 and I4, respectively. Said body member I0 isprovided with an opening I9 in which is disposed a manually operablevalve or plug 20 containing a passage 2| extending through the diameterof the plug and a passage 22 at right angles to passage 2 I. It will benoted that said plug can be rotated to control the passage of fluidsthrough either passage 2I or 22 from passages I6 or I 'I in any desiredmanner into a passage 23 leading into a syringe needle 24.

Said needle 24, as shown, is provided with a channel 25 leading intopassage 23, and a channel 26 which, as shown, is in communication withpassage I5 and inlet I2 of body member II. The puncture end 21 of saidneedle 24 is provided with an inclined opening 28 disposed in theperiphery of said needle and forming part of channel 25. The otherchannel 26 is closed at its end but is provided as shown with a sideopening 29.

It will be noted that said side opening 29 and opening 28 in theinclined tip 21 of the needle, as shown in Figs. 1 and 3, are sodisposed that they do not extend too far from the puncturing tipvthereby avoiding too deep a penetration of said needle end into the bodyduring the use of the device.

The inlets I3 and I4, respectively, are provided with syringes 30 and 3I, respectively, of the usual type of construction, while inlet I2 isadapted to accommodate a closure member 32 containing a exible stem 33which is adapted to enter into inlet I2 and passage I5 into channel 26of the needle, while the rear or head portion 34 of said member 32 isadapted to form a seal with inlet I2 of body member II. Said `member 32is provided in order to close the channel 26 and permit penetration ofthe needle 24 to a certain depth into the body, whereupon the saidmember 32 said shell 31 is provided with a manually operable screwmember 39 at the end of which is a pressure plate ymember 40 which isadapted to press against said rubber tubing 38. Said shell 31 isprovided with an opening il through which a fluid, such as air, whichhas been initially cleaned can be passed but whose amount is controlledby means of said screw member 39 pressing against the rubber tube so asto restrict the size of said tube.

Plug 2B in body member il, it will be noted, can be rotated into anydesired position such as that shown in Figs. l and 2. It will be noted,furthermore, ythat said plug 2li can be rotated so that it forms acommunication between syringe member 3i) and channel 25 thus permittingthe injection of fluid through said channel while simultaneouslywithdrawing fluid from the body through the other channel 2S and outthrough passage l5. This operation, however, may be reversed so thatfluid can be withdrawn through said channel 25 by withdrawing the piston42 or 133 of syringe 3U or 3l, respectively, and simultaneouslypermitting a flow of another iluid through the regulator 35 into channel26 and thus into the body. It may be desired to inject two differenttypes of fluid into the body at different times while drawing out ailuid from the body by using the arrangement as shown in Fig. 1 inwhichcase the plug 20 may be turned as shown in Fig. l to permit injection offluid into the body by means of syringe 3l), then turning the plug 2U asshown in Fig. 2 so that the communication between the syringe 3l iseiected with channel 25, and then injecting another fluid into' the bodythrough said latter syringe 3l While at the same time forcing anotherfluid into the body through regulator 35 into channel 26. By propermanipulation of the plug 2B and syringes 30 and 3l connected with memberIl and the operation of regulator 35 and the use of the needle 24,several desired techniques may be developed, whereby different types ofuids may be alternately added to the body, or whereby various bodyfluids may be removed therefrom.

It will be noted from the foregoing description taken in connection withthe accompanying drawings that there is provided a medical devicecontaining one or more syringes and a needle construction in which oneof the channels of the needle is adapted for supplying a fluid into thebody while the other channel in the needle is adapted for extracting oreducting a fluid from the body. By the use of a dual channel needle suchas that described and forming part of my invention, a single punctureinto any cavity of the body permits injecting a substance either liquidor gaseous to displace the secretions, exudate pus, blood or gasautomatically from the body. Furthermore, the needle as described andshown and forming part of this invention, because of its dual channelpermits a constant inow and outilow of different fluids through thechannels. Because the location of the respective terminal openings atthe puncturing end of theneedle are in different positions, there islittle likelihood of the fluids entering or leaving the body beingimmediately mixed. The injected liquid should preferably be of adifferent specific gravity from the iluid being extracted from the bodycavity. In some instances, where it is desired to remove pus from acavity of the body, it is quite difficult by ordinary needle and syringeto remove said pus because of its thickness. By utilizing the deviceinvented by me and described herein, this pus can be diluted byinjecting a medicine or saline solution through one of the channels ofthe needle to permit intermixing of the pus and the medicine or salinesolution and then flowing the resultant mixture through the otherchannel of the needle, thus cleaning and washing the cavity containingsaid pus. It will be further noted that by utilizing the iluid controlregulator, the pressure in the cavity into which the needle has beeninserted can be kept constant during the operative procedure. This is anextremely important factor in rendering the patient comfortable and alsoin eliminating the possibility of shock and other dangerouscomplications formed through sudden change in pressure in a closed spacein the body, especially as in the case of pleural and lumbar punctures.

For example, my invention can be used for an ordinary diagnostic lumbarpuncture, in which case the gradual injection of air through the syringe3l into the spinal canal permits the spinal fluid to out through theregulator from channel 2E ci' needle 24. rlhe flow ci air bubblesentering through one of said channels is under controlled pressure bythe promanipulation of the iluid control regulator through channel 25,thereby balancing the pressure oi' spinal iuid coming from the bodythrough channel 25 of the needle. This sp al fluid may be collected insyringe or the spinal fluid can be measured in order to insure thatthere is not any great diierence in displacement of the spinal huid byair.

It will be noted that the device herein described can be 'used forpuncturing various parts of the body such as the joint cavities,sinuses, abscesses, arteries and veins and that in the hands of thephysician can be of great importance and assistance to him inalleviating pain in the body or in assisting him to obtain fluids foranalysis and proper diagnosis.

While a preferred embodiment of my invention has been described inconnection with the accompanying drawings, it is understood that variouschanges or modifications as to form, arrangement of parts, and use ofmaterials, may made without departing from the spirit and scope of theinvention as claimed.
